Brazilian defence contractor Avibras will join plane maker Embraer SA and the local unit of Israeli Defence Company Elbit Systems in developing unmanned aircraft in Brazil, the companies said on Tuesday.

President Dilma Rousseff revealed Monday that in the last four months Brazilian forces in the framework of the ‘Strategic Frontiers Plan’ had seized over 62 tons of drugs and 650 kilos of arms and explosives.

Chile confirmed it had purchased Israeli manufactured Unmanned Aerial Vehicles (UAV) which will be used for border surveying to control contraband and drugs. However the UAV won’t be operational for at least another two years.

Israel Aerospace Industries signed a joint venture with Brazil's Synergy Group to manufacture Unmanned Air Vehicles (UAV) (drones) to fight drug trafficking in Brazilian borders under the condition that the aircrafts are not sold to Venezuela.

Brazilian incumbent presidential candidate Dilma Rousseff revealed that Brazil is patrolling its border area next to Paraguay with an UAV (Unmanned Aerial Vehicle) hoping to control the inflow of narcotics, weapons and illegal merchandise (contraband).
